THE RIGHT TIME DBS Therapy For Parkinson’s Disease


The right time for DBS is when your medications still work, but not as well as they used to. Research shows that deep brain stimulation may be appropriate for people who have had Parkinson's for at least four years and at least four months of movement symptoms not well controlled by medications or medication side effects such as unintended movements (dyskinesia).1,2

You may be eligible for DBS if you have had a Parkinson's diagnosis for at least four years, have had movement symptoms or medication side effects for at least four months, you respond to Levodopa, and your movement symptoms are not adequately controlled with medication.

Parkinson's symptoms get worse over time. The right time for DBS is when medications alone aren't providing enough relief, but still have some effect. The right time to talk with your doctor about DBS is now — so you know all your options and can act at the right time.

You're probably taking medications to help control movement symptoms like tremor (shaking), slowed movement (bradykinesia), and stiffness (rigidity).

One common Parkinson's disease medication, levodopa, is typically very effective at first, but less so over time. As Parkinson's progresses, doctors prescribe more or different medications, and have you take them more often. The higher doses may not bring the relief you need and can lead to side effects like nausea, dizziness, or unintended movements (dyskinesia).


If you wait until your medications no longer help, DBS will no longer be an option — so don't think of DBS as a last resort. Instead of just putting DBS off until someday in the future, talk with your doctor about it now. That way, you will be ready to start at the right time for you.

Watch for these signs that your medications are not working as well as they used to:

  • You have movement symptoms like tremor and stiffness for more hours a day.
  • After you take a dose, you wait longer for your medications to work.
  • The medications' effects wear off between doses.
  • You have to take medications more often, including during the night.
  • You need a higher dose to get the same effect.
  • Side effects of your medications are becoming a problem for you.
